A dominant private student-loan incumbent priced like a sleepy bank—right as federal reform may force a historic wave of graduate borrowing into its lap.
Overview
SLM Corp (Sallie Mae) is the dominant U.S. private education lender, with an estimated ~63% market share as of FY2025, benefiting from deep integration across 1,500+ school financial aid offices, strong brand equity, and a deposit-funded banking platform. The business earns through (1) net interest income on loans held for investment—supported by high asset yields (~10.46% in Q1 2026) versus a managed cost of funds (~4.13%)—and (2) non-interest “gain-on-sale” income via whole-loan sales to institutional investors (Q1: $3.3B sold, $146M gains). Credit quality is positioned as strong (average approval FICO ~754; ~95% of undergrad loans cosigned). The forward thesis is dominated by OBBBA reforms that remove Grad PLUS and cap Parent PLUS in mid-2026, potentially driving large origination growth, while management simultaneously accelerates buybacks and uses loan sales to keep the balance sheet from ballooning.
